Miniature rose plant named Poulvok

ABSTRACT

A miniature rose plant having bright red flower color, compact dwarf growth habit, long shelf life, and ease of propagation from softwood cuttings.

The present invention relates to a new and distinct variety of rose plant of the miniature class which was originated by us by crossing two unnamed seedlings.

The primary objective of this breeding was to produce a new rose variety having a dwarf, compact plant habit; ease of propagation from softwood cuttings; an attractive, clean, bright red flower color; and good shelf life as a pot or garden rose. The objective was substantially achieved, along with other desirable improvements, as evidenced by the following unique combination of characteristics that are outstanding in the new variety and that distinguish it from its parents, as well as from all other varieties of which we are aware:

1. Bright red, attractive flowers;

2. Compact dwarf habit;

3. Ease of propagation from softwood cuttings; and

4. Good pot rose shelf life.

Asexual reproduction of this new variety by softwood cuttings as performed at Wasco and Somis, Calif., and Fredensborg, Denmark, shows that the foregoing characteristics and distinctions come true to form and are established and transmitted through succeeding propagations.

The accompanying illustration shows typical specimens of the vegetative growth and flowers of this new variety in different stages of development, depicted in color as nearly true as it is reasonably possible to make the same in a color illustration of this character.

The following is a detailed description of our new rose cultivar with color descriptions using terminology in accordance with The Royal Horticultural Society (London) Colour Chart, except where ordinary dictionary significance of color is indicated.
